Abstract

Housing for a vacuum pump, in particular a NEG or IGP-NEG combination, comprising a body defining an interior space to accommodate the vacuum pump, wherein a first flange is connected to the housing comprising an opening to connect the vacuum pump to a vessel and a second flange connected to the housing to connect the housing to an additional vacuum pump at least during regeneration. Further, a movable shield element is used movable from a first position to a second position, wherein in the first position the opening of the first flange is unobstructed and in the second position the opening is blocked.

Claims

exact text as granted — not AI-modified
1 . A housing for a vacuum pump, in particular a NEG or IGP-NEG combination, comprising:
 a body defining an interior space to accommodate the vacuum pump,   a first flange connected to the body and comprising an opening to connect the vacuum pump to a vessel, and   a second flange connected to the body to connect the housing to an additional vacuum pump at least during regeneration,   characterized by   a movable shielding element disposed inside the interior space of the body and movable from a first position to a second position wherein in the first position the opening of the first flange is unobstructed and in the second position the opening is blocked without completely sealing the interior space from the vessel.   
     
     
         2 . The housing according to  claim 1 , characterized in that no vacuum valve is arranged at the first flange. 
     
     
         3 . The housing according to  claim 1 , characterized in that the shielding element comprises a magnetic element connected with a magnetic handle outside the body to transfer the movement of the magnetic handle to the shielding element. 
     
     
         4 . The housing according to  claim 1 , characterized in that the shielding element is a sheet metal element. 
     
     
         5 . The housing according to  claim 1 , characterized in the shielding element comprises no sealing. 
     
     
         6 . A vacuum pump comprising a NEG element and/or an IGP element and a housing in accordance with  claim 1 . 
     
     
         7 . A vacuum system comprising a vacuum pump according to  claim 6  and a vacuum vessel directly connected to the vacuum pump.
